I was using XnView Shell Extension version 3.5.1, unregistered it, downloaded the new version (XnShellEx64.zip), replaced the files, registered it and it worked. So far so good. I noticed that in 'Options' - 'Displayed Menu items' there was a change - 'File's icon' was replaced with 'Resize', so I enabled it. 'Resize' appeared in Windows shell but the drop-down menu did not work:

Compare it with for example 'Rotate', showing drop-down menu just right:

Am I missing something or this is a bug?

By the way I could not find the change log for the latest version which I am not sure whether it is 4.0.0 as shown in 'About' or 4.0.1 (file version shown as 4.0.1.0).

After watching your video, it seems to me this problem has nothing to do with XnView Shell Extension, maybe it's a SO or Photoshop related issue. Have you tried to check on the Photoshop memory settings?

Just checked, i uninstalled shell extension and freezing is gone, right button menu appears fine

One more question: the menu used to freeze when you opened the context menu within the Photoshop Save as dialog, right?

If so, maybe the integration of the extension with the OS shell plus the Photoshop dialog box is the reason for the freezing. But it's just a guess.

yes, it is freezing only photoshop, explorer is working fine during this freezing. But i remember what before it was works, it may what my OS has problem, so i am asking to check somebody who have photoshop.

I just made a test here, but with Corel Photo-Paint (I don't have Photoshop). I created and saved one simple PSD file. With it still opened in the program, I opened the Save as dialog again, clicked on the very same file I've just saved to launch the context menu and the XnView Shell Extension showed the file's thumbnail — from within the Photo-Paint Save as dialog — without freezing.

Maybe it's also a matter of file size, memory, etc. Just thoughts to help you find a fix. Good luck!
